Gauge Pressure Switch P11B Series

The P11B's welded stainless steel bellows sensor meets the flameproof requirements of the aviation industry making it suitable for low-pressure hydraulic applications. In addition, the bellows leak tight integrity (1x10-8 std cc/sec) makes this design perfect for closed gaseous systems. Welded bellows have unbeatable media compatibility, sensitivity and repeatability. These features combined with a negative rate Belleville spring create a shock and vibration resistant package less than 0.875" in diameter.
